From lawnmowers, to barbecues, to booking a hotel room. Why the price is different if you buy from your phone instead of your home computer. Good evening. Its great to have you with us on a friday night. We begin with breaking developments involving james comey, set to testify next week before the american people. Tonight, abc news has learned lea hes prepared to talk about what he wrote in his memos, and whether he felt pressured by the president in the russia investigation. The white house asked if hes going to block the testimony. Heres pierre thomas. Reporter tonight, as fired fbi director james comey prepares to testify before the american people, the white house will not say whether President Trump might try to stop him. When asked if the president will invoke executive privilege over his meetings with comey, the press secretary acknowledges tonight, no decision has been made. And theyre not ruling out the idea of blocking comey. I think, obviously, its got to be reviewed. So is that thats not a no . No, i was just saying, i dont it literally my understanding is the date for that hearing was just set. Ive not spoken to counsel yet. I dont know what theyre going to how theyre going to respond. Reporter counselor to the president Kellyanne Conway said today its up to the president. The president will make that decision. Reporter comey is expected to testify before the Senate Intelligence committee, where he will be asked about his private meetings with the president. Whether comey was asked for a pledge of loyalty from President Trump, and whether the president asked him to go easy on michael flynn, who lasted 24 days on the job. And congress is expected to ask comey about what could be the most revealing piece of evidence yet those memos comey privately kept after his meetings with the president. The firing of comey came after the president once joked with him, youre becoming more famous than me. Weeks later, allegedly calling comey a nut job in the oval office with the russians. But tonight, some legal scholars say if the president tries to stop comey from testifying, it could be a tricky move. That invoking executive privilege at this stage could be a challenge. Especially because President Trump has already spoken publicly himself about his private meetings with comey. Comey better hope there are no tapes about our meetings. And saying this about their private dinner. We had a very nice dinner and at that time he told me you are not under investigation. The concern is that by publicly commenting and tweeting about discussions hes had with comey, the white house itself might have inadvertently waived the privilege. Reporter abc news has learned tonight that comey is angry and wants the public to understand his side of the story. And he is prepared to answer questions over memos he drafted detailing some of his conversations with President Trump. In one memo, comey is said to have recounted how the president suggested the fbi should drop its investigation of general mike flynn. I hope you can see your way clear to letting this go, to letting flynn go, comey quoted President Trump as telling him that day. But the major question tonight, will comey bring his memos to capitol hill . Some democrats want him to read them aloud. Pierre, will the public see the memos for themselves . Reporter thats still unclear. Sources tell us we may not know until just before the hearing. David . Pierre, thank you. In the meantime next this evening, the fallout after President Trumps decision to pull out of the paris accords. Tonight, the white hou pressed. Does the president believe Climate Change is real . Heres mary bruce. Reporter with the world in shock, the white house today giving a staunch defense of the president s controversial decision. Paris represents a bad deal for this country. It doesnt mean that were not going to continue the discussion. Reporter but when pressed, the administration wont say if the president thinks Climate Change is even a problem. Yes or no, does the president believe that Climate Change is real and a threat to the United States . You know, its interesting about all the discussion we had during the last several weeks have been focused on one singular issue, is paris good or not for this country. Reporter but on Climate Change, yes or no . Yes, maam . Reporter and the press secretary says he still hasnt talked to the president about his campaign claim that Climate Change is a hoax. I have not had the opportunity to have that discussion. Reporter but from mexico city to new york to paris itself, buildings bathed in green in support of the agreement. The new french leader has made clear hes not afraid to take on trump, admitting this whiteknuckle handshake was not innocent. Late thursday making this rare address in english.

Next, russian president Vladimir Putin with a message about President Trumps decision. And what he said about the idea of Russian Hackers in the election. And this question, was President Trump ready to lift sanctions on russia with nothing in return just days into his administration . Heres david wright. Reporter the russian president took the stage, to go easy on President Trumps decision, using a phrase in english. Dont worry, be happy. Reporter and putin blamed the democrats for the hysteria over the hacking of the campaign. And in his most belittling tone, the russian president claimed the clinton camp was acting like an antisemites. But u. S. Intelligence says theres plenty of proof for the hacking. One reason why investigators want to question president ial soninlaw Jared Kushner. Was his meeting with gorkov. Was it part of a russian influence operation . Reporter just yesterday, abc news tracked down gorkov, but he wouldnt answer questions. As did the white house, other than this one. Does the president still have confidence in Jared Kushner . Absolutely. Reporter we also just learned, just weeks after president obama expelled the russian compounds. The sanctions would be lifted. I didnt see any american interests being served by giving putin something for nothing. Reporter for now, they remain in effect. With insiders saying the situation is just too hot. David .

Back here at home, the white house has asked the Supreme Court to weigh in on its travel ban. It has been blocked by lower courts. The administration argues the ban is about national security.

If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising.
